    Abstract:
    AIMS: This study aimed to determine the influence of carotid artery surgery on ocular functions and ocular blood flow in patients with ocular ischaemic syndrome (OIS) in the late postoperative period. METHODS: One hundred and eighty patients with OIS were operated on; 104 of them suffered from acute forms of the ischaemic disease and 76 patients had chronic forms of ocular ischaemia. Before surgery and in the course of 6 months and 12 months afterwards, all the patients were examined. Visual acuity, electrophysiological investigations (the threshold of electrical sensitivity (TES) and the level of liability of optic nerve (LON)) and blood flow in orbital vessels were assessed. RESULTS: After surgery visual acuity increased in patients with the acute forms of OIS (P<0.05). TES and LON also improved (P<0.01). Mean indices of blood-flow velocities in the ophthalmic artery, the central retinal artery and the posterior ciliary arteries increased at 6 and 12 months after surgery (P<0.05). There was ocular blood flow acceleration and decrease of vasoresistance in orbital arteries in both groups of patients. CONCLUSIONS: Carotid artery surgery effectively improved ocular blood flow in patients with acute and chronic forms of OIS in the late post operative period.
